What is the primary concern when performing chemical treatments on hair?

The primary concern when performing chemical treatments on hair is avoiding damage to the hair. Chemical treatments, such as coloring, perming, or relaxing, involve the use of powerful substances that can alter the structure of the hair. These processes can weaken hair or cause adverse effects if not done properly or if the hair is already compromised.

Hair can become dry, brittle, and prone to breakage when subjected to harsh chemicals, so it's crucial for cosmetologists to prioritize the hair's health throughout the application. This includes evaluating the hair's condition before treatment, using appropriate products, and following safety protocols to minimize any potential damage. By focusing on preserving the integrity of the hair, professionals can ensure that clients leave with not only the desired style or color but also healthy, manageable hair.
